Since BÜTTNER ELEKTRONIK was founded almost 30 years ago, we have been exclusively concerned with solar technology and on-board electronics for recreational vehicles. For more than 20 years now, we have also published our manual, in which we try to provide you, our customers, with comprehensive information. In the manual and also here on our homepage, we are not concerned with simply presenting a product in a sales-promoting manner. We want our customers to be informed about what the respective product can do and also where the limits might be. Only then will you, the customer, be satisfied and be able to judge whether the targeted device or the complete system fully meets your requirements.
In many internet forums you can read "Get the manual from Büttner first". Reading something like this fills us with joy and confirms our claim. Sometimes this tip is taken up by another participant, with the recommendation to then look for a cheaper device on the Internet. Be sure, there will always be someone who offers cheaper and pretends to be just as good as the original. On closer inspection, however, it usually turns out that the solar modules are just mass-produced and only the frame was painted black. Or that the regulator is supposedly suitable for all on-board batteries, although it has no temperature sensor and cannot be adjusted for AGM or lithium batteries. Furthermore, it becomes more difficult when only a simple device fan is installed in the plastic or sheet metal housing of the charger or charge booster in order to save costs. This may work in the laboratory. In the motorhome it looks quite different. There is no ventilation and if the vehicle has heated up, these devices can not help but regulate back, because no heat can be dissipated through the housing. This is only one example of many, why we equip our devices with a special housing profile. Be that as it may, our aim is to develop products for you which fully meet your expectations and which you will enjoy for a long time. Find out more about our products and complete systems in this manual, then take your time to decide whether the product is right for you.
We would be pleased to welcome you as a satisfied customer.
Thank you for your trust,
